Resumen de: US2025317304A1
A system and a method for efficient, safe, and eventually guaranteed block registration on distributed ledgers, using a protocol family named Cordial Miners is disclosed. The disclosure comprises three exemplary embodiments of a distributed ledger block registration protocol. The disclosed protocol may be used as a blockchain consensus protocols that shares a partially-ordered data structure and an ordering algorithm. The data structure may be a generalization of the totally-ordered blockchain, and referred to as blocklace. The ordering algorithm may convert the partially-ordered blocklace into a totally-ordered sequence of blocks, while excluding non-valid blocks such as equivocations.

A method includes a computing device verifying authenticity of a blockchain-encoded record representing a statement of words and an entigen group to produce an authenticity indicator where a set of identigens is determined utilizing a knowledge database for each word to produce sets of identigens and where the sets of identigens is interpreted to produce the entigen group. When the authenticity indicator indicates an authentic status, the method further includes interpreting, based on an updated knowledge database, updated sets of identigens to produce an updated entigen group. The method further includes updating the blockchain-encoded record to represent the statement and the updated entigen group to facilitate subsequent utilization of an updated validated interpretation of the statement as the updated entigen group.

A system and method providing Proof of Location or Proof of Location and Velocity consensus in a blockchain network using radio frequency (RF) signals. Nodes validate the location of other nodes in the network using PING-PONG round trip signal propagation time to determine maximum distances to other nodes. These maximum distances are then shared between nodes, whereupon the nodes use computational techniques to resolve validated, geospatial location of the other nodes. The sharing of measured maximum distances to local nodes is a form of Proof of Location consensus. The validated geospatial locations (and velocities) of local nodes are then written to the blockchain, creating a time history for each node. This information may be used by the blockchain operating rules to implement any number of security and other operational functions. The ability of the invention to operate without need for time synchronization between nodes is an advantage of the system.

A blockchain-based SDP access control method and apparatus. An SDP connection initiation host submits identity authentication request information to a blockchain system node, and an authentication result after verification is fed back to the SDP connection initiation host; the SDP connection initiation host sends, to the blockchain system node, a query request for an SDP connection accepting host list that can be accessed, wherein the query request comprises an authentication result of the blockchain system node for the SDP connection initiation host; after verifying the query request, the blockchain system node queries the SDP connection accepting host list that can be accessed by the SDP connection initiation host, and records the SDP connection accepting host list to a blockchain ledger; the SDP connection initiation host initiates a connection request to the SDP connection accepting host, queries the SDP connection accepting host list that can be accessed by the SDP connection initiation host; and if an SDP connection accepting host to be accessed exists, then access service is provided, thereby avoiding DDoS attacks on an SDP controller, and preventing the SDP controller from implementing incorrect authorization.

Systems and methods for blockchain-based asset authentication are described. The disclosed embodiments leverage the traceability and immutability of blockchains (or distributed ledgers, in general) to enable the authentication and ownership of assets, e.g., luxury goods. In an example, this is achieved by first pairing an authentication chip with a physical product, and writing a transaction correlated with the first pairing to a blockchain. The product being acquired (reacquired) results in the blockchain being updated (e.g., an updated transaction being written to the blockchain) and the (subsequent) owner being provided with a digital passport that can be added to the owner's digital Web3 wallet. The described embodiments advantageously enable digital identities to be associated with physical goods, which adds value for customers making a long-term investment in a luxury good, and promotes sustainability and transparency in manufacturing and retail processes.

Embodiments of the disclosure provide solutions for facilitating exchanges of blockchain tokens between users. In a preferred embodiment a computing platform is provided which matches exchange-related instructions (orders) that are received from respective users. Each user establishes at least one payment channel with the platform and funds it with tokens of the type specified in their exchange-related instructions. When matching instructions are identified by the platform, the exchange is performed via the payment channels. A multi-party atomic swap can be used for implementing the token exchange, in which spending of a first transaction reveals a secret that can be used to spend a further transaction.

A system for sharing a distributed revocation list on a blockchain includes circuitry that identifies access attempts of a wallet on a first blockchain network and adds the wallet to a blacklist. And the blacklist identifies the wallet as a suspicious wallet. The circuit system generates a soul binding token, and the soul binding token is air-dropped into the wallet. And the soul binding token identifies that the wallet belongs to the distributed revocation list and identifies that the wallet is a suspicious wallet to a block chain network.
